I haven't been on in a while...
But, I have found that I have a burnt valve on #4...
A while back I replaced everything on the topside from the manifold gaskets up..New Billet Distributor,
New updated Spider, Fuel Regulator, you get the idea.
I kept getting a miss on #4...I thought it had to do with the manifold gaskets leaking...Well, after I changed everything the miss was gone...for a day.
I started running some Marvel Mystery Oil through it and it got worse...Evidently the Marvel cleaned the carbon off the valves and the miss really came on strong...I done the dollar bill test and it nearly sucked the bill out of my hands. Bummer!
Well, I figured it would be a good chance to upgrade the valve train on my Limited. So I went to the Pick a Part (LKQ) and got a great deal on a pair of 062 heads. I cleaned them up real good and didn't find any cracks so I hope I dodged a bullet with that.
I'm porting the exhaust on the heads at the moment and they're coming out really nice. Got one head done and started the other tonight.
I went through the threads that had anything to do with Vortec heads and only found one person that had any knowledge of the Vortec head...I won't call any names but I'm sure he knows who he is and has given me good advice before.
Here is my rendition of upgrading a Vortec head on a tight budget...
I want to use the Z28 springs along with a set of 1.52 rollers (if I can find a good deal) if not, I've got a complete set of OEM rockers,pushrods and roller lifters from a wreck with 9000 miles on it.
I've been studying the Vortec head for a good while now and I seen some advice given that was totally wrong for the head.
First...You don't have to port match the Vortec unless you plan on rpm's over 6500 then you might do some port matching.
If any of you are like me your truck very rarely see's 5000 rpm's but every now and then I will pull a car dolly/car trailer/utility trailer and I would like a little more usable power and torque for job at hand.
I would like some input...good input on what you all think would be the best way to upgrade these heads for daily driving and occasional towing...My Hoe won't be seeing the drag strip anytime soon so please state your version of a budget build for a Vortec head.
